Abstract
The invention relates to a fire retardant and a preparation method thereof. The fire retardant is prepared from the following components in parts by weight: 23 to 28 parts of triphenyl phosphate, 16 to 22 parts of diammonium hydrogen phosphate, 5 to 10 parts of magnesium hydroxide, 3 to 10 parts of diatomite, 1 to 3 parts of silane coupling agent and 37 to 47 parts of water. The preparation method comprises the following steps of: heating; stirring; smashing; and heat preservation. The prepared fire retardant is good in flame retardance and environmental friendliness, and can be widely applied to the fields of plastics, rubbers and the like.
Description
Technical field
The present invention relates to a kind of auxiliary chemicals, more specifically relates to a kind of fire retardant and preparation method thereof.
Background technology
In order to adapt to social safety needs, reduce the possibility that fire occurs, among fire retardant is being widely used in production and is living.At present on the Chinese side, occupied more than half market of China containing brominated flame retardant.But there is development toxicity, disturb secreting function, genotoxicity and this carinogenicity containing the decabromodiphenyl oxide homologue that brominated flame retardant produces, and the content of this type of decabromodiphenyl oxide homologue in human body increases day by day, the fire retardant of developing a kind of novel environment friendly has been current faced instant problem.
Summary of the invention
The technical problem solving: for the problems referred to above, provide the fire retardant of a kind of environment-protecting asepsis, with low cost, good flame retardation effect.
Technical scheme:
The invention discloses a kind of preparation method of fire retardant, fire retardant is made up of according to weight part following composition: triphenylphosphate is that 23～28 parts, Secondary ammonium phosphate are that 16～22 parts, magnesium hydroxide are that 5～10 parts, diatomite are that 3～10 parts, silane coupling agent are that 1～3 part, water are 37～47 parts.
The preparation method of fire retardant, comprises the steps: that (1) get 37～47 parts of 16～22 parts of Secondary ammonium phosphates, water and add in reactor, and temperature of reaction kettle is risen to 90～100 DEG C; (2) mixing speed be under 80～100rpm, add fast and evenly 23～28 parts of triphenylphosphates, 5～10 parts of magnesium hydroxides, 3～10 parts, diatomite, 1～3 part of silane coupling agent, mixing speed be 60～80rpm stir 3h; (3) be cooled to after room temperature, white depositions is filtered, after centrifugal drying, be products obtained therefrom.
A kind of fire retardant, triphenylphosphate is preferably 25 parts
.
A kind of fire retardant, Secondary ammonium phosphate is preferably 18 parts.
A kind of fire retardant, magnesium hydroxide is preferably 7 parts.
Beneficial effect: the few feature of nontoxic smog when the fire retardant that the present invention prepares has burning is a kind of environmental protection based flame retardant; Good flame retardation effect and can be widely used in the field such as plastics, rubber.
Embodiment
Embodiment 1
The preparation method of fire retardant, comprises the steps: that (1) gets Secondary ammonium phosphate 18kg, water 42kg adds in reactor, and temperature of reaction kettle is risen to 90～100 DEG C; (2) be that under 80～100rpm, to add fast and evenly triphenylphosphate 25kg, magnesium hydroxide 7kg, diatomite 6kg, silane coupling agent 2kg, mixing speed be to be 3h 60～80rpm time at mixing speed; (3) be cooled to after room temperature, white depositions is filtered, after centrifugal drying, be products obtained therefrom.
Embodiment 2
The preparation method of fire retardant, comprises the steps: that (1) gets Secondary ammonium phosphate 22kg, water 47kg adds in reactor, and temperature of reaction kettle is risen to 90～100 DEG C; (2) be that under 80～100rpm, to add fast and evenly triphenylphosphate 23kg, magnesium hydroxide 5kg, diatomite 10kg, silane coupling agent 3kg, mixing speed be to be 3h 60～80rpm time at mixing speed; (3) be cooled to after room temperature, white depositions is filtered, after centrifugal drying, be products obtained therefrom.
Embodiment 3
The preparation method of fire retardant, comprises the steps: that (1) gets Secondary ammonium phosphate 16kg, water 37kg adds in reactor, and temperature of reaction kettle is risen to 90～100 DEG C; (2) be that under 80～100rpm, to add fast and evenly triphenylphosphate 28kg, magnesium hydroxide 10kg, diatomite 3kg, silane coupling agent 1kg, mixing speed be to be 3h 60～80rpm time at mixing speed; (3) be cooled to after room temperature, white depositions is filtered, after centrifugal drying, be products obtained therefrom.
Fire retardant prepared by embodiment 1, embodiment 2, embodiment 3 is according to 20%(wt) addition join respectively in 40D terylene, and compare with the 40D terylene that does not add fire retardant, according to GB/T 5454-1997 test oxygen index testing level combustionproperty.
| ? | Comparative example | Embodiment 1 | Embodiment 2 | Embodiment 3 |
| Oxygen index (%) | 20 | 28 | 25 | 26 |
| Horizontal firing speed (mm/s) | 5.5 | 2.3 | 2.8 | 2.5 |
Test result shows, adds the horizontal firing speed of the 40D terylene of embodiment 1-3 fire retardant to have great raising, compares with the 40D terylene that does not add fire retardant, and oxygen index is also significantly improved.Illustrate that fire retardant of the present invention has possessed better flame retardant effect, and there is the nontoxic feature of environmental protection, can be for the multinomial field such as rubber, plastics.
